Klout, a site that measures your influence on social media, is about to be sold for at least $100 million to Lithium technologies, according to Recode. The deal isn't closed, but papers have been signed, according to the report.

Lithium Technologies makes tools that brands can use to provide customer service on social networks.

The acquisition makes sense. It would be very helpful to brands to know how influential people tweeting about their products and services are. Klout gives social media users a score on a 100-point scale that measures their influence based on a secret algorithm.
